Federal prosecutors say the other 29 people charged already have pleaded guilty to roles in the racketeering conspiracy.

Holland Director of Public Safety Matt Messer said the convictions made the city safer.

“We are pleased with outcome of this lengthy investigation that has had a substantial positive impact on the Holland area and has solved crimes reaching back over the last three decades. And we appreciate the local and federal collaboration on this case that resulted in the successful prosecution of 31 high ranking members of the Latin Kings gang," he said.
